Signy Island - Preparation of a
dive-hole to go diving under the sea ice. The snow has been pushed
back from the surface and this saw with a special ice blade is
being used to cut a hole through the ice. Once cut, the floating
square is cut into quarters and the then each quarter pushed under
the ice where it's buoyancy keeps it in place. Not too bad a job
until you hit the sea, then the blade sprays you with
exceptionally cold water - 1985
